I agree with this. I don't think guilt is a good reason to do much of anything, and I think that being clear in one's morals and honest with those around them is a good thing.
But I think it can be difficult to do that in way that still nurtures our relationships with people who feel differently than us and yet are important to us, such as our grown children. How to stay true to ourselves and yet still stay connected to those we love who feel differently is difficult.
I don't see the answer as simplistically as just avoiding saying anything that another could take offense at, because staying true to ourselves still needs to be part of it. It's a dilemma.
Smokering, I'm sure we have more in common than we have different, even though we have different perspectives on this difficult and devise issue.
